Also, do I teach her how to use the lawn tractor or let her suffer through trying to figure it out herself. I'm guessing that I should be nice and show her, but I always seem to do the wrong thing, so I thought I'd ask for advice.
Offer to mow the lawn for her for the next couple weeks. This way you get to spend an extra night with the kids, and she might even invite you in for dinner or bring you a glass of sweet tea.
